Legs: Claw with single inner tooth at three-quarters. Empodial appendage two-thirds as long as claw, with broad inner lamella truncated at two-thirds and narrower outer lamella reaching to apex. Two clavate tenent hairs longer than claw to each foot.

Furcula: Very short, manubrium to dens to mucro as 15: 11: 4. The mucro tapering to small apical tooth. Dens with two very long ventral setae almost as long as itself.

Locality: Te Whaiti, Urewera Country, on the trunks of willow trees growing on the river bank.

Colour: In life a very dark blue; mounted specimens show a uniform deep blue-black.

Body: Length 1·25–1·5 mm. Clothed with short hairs, longer setae occurring around posterior region. Tergum of mesothorax completely covers prothorax and is related to head as 12: 22. Antennae four-segmented, the segments related as 5: 8: 5: 10, slightly longer than head. Ocelli eight to each side, seven large and one small. Post-antennal organ approximately equal in length to two ocelli diameters and elliptical. Ventral tube small. Abdomen IV to Abd. III as 15: 9. Abd. VI hidden under Abd. V.

Legs: Lightly clothed with long setae. Claw with single internal tooth about halfway from base of claw. Empodial appendage lanceolate with broad inner and narrower outer lamellae. Single tenent non-clavate hair to each foot, longer than claw.

Furcula: Short, manubrium: dens: mucro as 6 : 3 : 1. Mucro tapering with single terminal upturned tooth. A pair of long setae ventrally placed at distal end of manubrium and two long ventral setae on dens. A long dorsal seta arises from end of dens and reaches almost to tip of mucro.

Legs: In his original description, Carpenter stated the claw was without teeth; but I now find on re-examining his specimens that the claw has a strong inner tooth just beyond the centre; no outer teeth. Empodial appendage from one-third to a half as long as claw, with broad inner and narrow outer lamellae. Front feet with one, others with two clavate tenent hairs about as long as claws.

Furcula: Dens about twice length of mucro and with at least two long ventral setae. Mucro lightly curved and tapering, without teeth, but with narrow inner lamella.

Locality: Described originally from a large number of species collected at Ben More, Canterbury. Not found elsewhere since.

Paratypes: In the Canterbury Museum, Christchurch, New Zealand. Two paratype slides, 3/985 and 3/986, in the Dominion Museum Collection.

Colour: In life a brilliant blue. Mounted, a clear prussian blue, varying from pale to dark, with the head, legs, and antennae violet. The ocelli on black pigment patches. Pale, almost colourless inter-segmental bands may be present on the anterior margins of all segments.

Legs: Claw with single very small inner tooth a little past half-way down. No outer teeth. Empodial appendage about one-quarter length of claw with very broad inner lamella reaching halfway to apex, and outer lamella which reaches tip. Two long clavate tenent hairs to each foot.

Furcula: Dens with three prominent ventral setae. Mucro long and tapering, with apical tooth and short backwardly-sloping sub-apical tooth. Dens related to mucro as 3: 2.

Localities: I have taken large numbers of this really beautiful species from Kidd's Bush, on the shore of Lake Hawea, in old logs and leaf debris; and from Peel Forest, Canterbury, under the bark of totara trees.

Colour: In life and mounted jet black all over, with sometimes, in mounted specimens, bluish tinge.

Clothing: Sparsely clothed with plain setae.

Body: Length 1·2 mm. Antennae slightly longer than head, four segments related as 2:8:6:12. Sensory knob at tip of Ant. IV Ocelli eight to each side, six large and two, posterior inner two, small. Post-antennal organ large and about size of two ocelli. Head related to meso-thorax as 47:27 and Abd. III to Abd. IV as 16:22. Ventral tube short and dome-like.

Legs: Claw with single inner tooth a little past half-way. No outer teeth. Empodial appendage about half as long as claw with outer lamella reaching to tip and broad circular inner lamella reaching about half-way. Two long clavate tenent hairs, longer than claw, to each foot.

Localities: Lake Mapourika, under the bark of kahikatea trees; Ferguson's Bush, West Coast, under the bark of rimu trees; Lake Te Anau, under the bark of rimu trees; Bullock Creek, South West-land, under the bark of rimu trees; Lake Brunner, in bush soil and debris; Fish River Gorge, Haast Pass, under the bark of totara trees.
